THOMAS C. OCTIGAN, OF CHICAGO, ILLINOIS; NORA MARY OCTIGAN EXECUTRIX 0F SAID THOMAS C. OCTIGAN, DECEASED.

HORSESHOE.

Application filed July 19. 1912.

To all whom it may concern Be it known that I, Tnoams C. OCTIGArI, a citizen of the United States, and a reeldent of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Horseshoes; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, and to the characters of reference marked thereon, which form a part of this specification.

This invention relates to improvements in horse shoes, and refers more specifically to the type of shoes provided with a rubber or other resilient tread surface.

Among the objects of the invention is to provide an improved horse shoe of this character in which the heel of the foot is protected from injury at the time when the foot strikes the roadway, so arranged that the impact due to the first contact of the shoe with the roadway is borne principally by the walls of the hoof and is resiliently transmitted to the heel of the foot. It is well known that when a horse places its foot upon the roadway the foot is brought down upon the roadway heel first, so that if the heel portions of the shoe are carried back in the plane of the body of the shoe, the heel receives the direct impact of the first blow on the roadway and is liable to bruises and injury. To this end the metal frame of the shoe is offset at its rear or heel ends below the plane of the main portion of the shoe, which supports the walls or quarters of the hoof, and to said oflset portions of the heel of the shoe are applied yielding cushions which protect the heel of the foot against injury when the foot first strikes the roadway.

The inventionconsists in the matters here inafter set forth and more particularly pointed out in the appended claim.

Figure 1 is a bottom plan view of a horseshoe embodying my invention. Fig. 2 is a top plan view of the metal frame or body of the shoe. Figs. 3 and l are detail sections on the lines 3-3 and ll, respectively, of Fig. 1. Fig. 5 is a side elevation of the heel end of the metal body of the shoe.

The curved body or bar of the shoe 10 is provided at its lower side with inner and outer calks 11, 12, respectively, forming be- Specifieation of Letters Patent.

tween the same a channel 1-1 to receive a body 15 of rubber or like friction material.

16, 16 designate the heel ends of the shoe in which the calks 11 and 12 are continued to constitute the walls 17, 17 of recesses 18, 18 to receive thickened cushion heel members 19 which are made of a depth greater than the main portion of the shoe, as best shown in Fig. 3. The heel ends 16 of the metal body of the shoe are offset below said main body of the shoe, as clearly indicated in Figs. 3 and 5, and in the said ollset portions, at the upper sides thereof, are mounted cushioning bodies 21, 21, as most clearly shown in Figs. 3 and 4. Also the calks or walls 17 of the heel extensions are offset below the planes of the calks 11 and 12 of the main body of the shoe so as to give a desired width to said ealks or walls to strengthen the heel ends or extensions of the shoe. It will be observed that the said rubber or resilient cushions 19 completely embed the calks or walls of the heel ends or extensions of the shoe and extend to a plane substantially below the lower edges of said walls or calks, so as to afford at the heel ends of the shoe a substantial cushioning body to receivethe first impact of the shoe when it first strikes against the roadway, as will be clear from an inspection of liigs. 1, 3 and .ir. The said heel ends or extensions 16 are provided with openings or slots 22 whereby the upper and lower heel cushions 21 and 19, respectively, may be bonded or integrally connected.

The rubber or other resilient material is applied to and molded upon the shoe as a single or integral part, the connecting members or bonds extending through the said openings 22, at the heel ends of the shoe. The rubber is thereafter subjected to a vulcanizing process to suitably toughen the same.

The body of the shoe is provided outside of the outer calk 12 with the usual nail holes 24: through which are adapted to extend the nails by which the shoe is attached to the foot of the animal. Said outer calk 12 is thickened at the toe of the shoe to provide the usual toe calk 25, and the toe of the shoe is provided at the upper side thereof with the usual toe clip 26.

The presence of the offset heel portions of the shoe, provided in the offset parts thereof with the cushioning pads 21, 21 serves to prevent the tender heel portion of the foot coming in contact with the rigid parts of the shoe when the foot first strikes the roadway. The shoe may be so fitted as to space the heel ends or extensions of the shoe from the tender heel portion. of the foot. Even if said heel portion is fitted a gainst the cushioning pads of the heel portions or extensions of the shoe and is brought directly against the cushioning members or pads when the foot first strikes the roadway, the presence of said cushioning members or pads will permit the same to yield sufficiently to protect the heel of the foot. Moreover, the rigid portion of the shoe body directly receives the wall of the heel at a point in advance of the offset portion of the shoe body, so that the principal part of the effect due to the first impact of the foot against the roadway is taken by the part of the shoe in front of said ollset. The carrying of the calks or walls of the shoe throughout the lower sides of the 05- set extensions thereof serves to greatly stiffen the heels of the shoe, notwithstanding that said heel portions are separated from each other and are not intersupported by a cross brace or bar. Moreover, the offsetting of the lower calks or walls of the heel extensions serves to strengthen the shoe body at the offset portion thereof and gives added durability to the shoe.

' It will be seen that the calk walls 17, of

the offset shoe ends, provide lateral engagshown, by disposing said calk walls in surrounding or housing relation with respect to said bodies.

I claim as my invention A horse shoe comprising a body portion with heel ends spaced apart from each other and comprising body webs with calk walls projecting at an angle thereto and eX- tending from the body portion to and around the heel ends, said heel ends and their calk walls being oiiset downwardly from the plane of the upper side of the body portion to dispose the lower edges of the calk walls of the oifset heel ends below the lower edges of the call: walls of the body portion, thereby stiffening the heel ends, and separate cushioning bodies unconnected to each other and embedding the webs and the call: walls of the offset heel ends, whereby the embedded heel end webs and their calk walls present angularly disposed faces resisting displacement of the cushioning bodies in any direction from normal, the upperportions of said cushioning bodies being extended above the webs of the offset heel ends and the lower portions being extended below the lower edges of the oiiset calk walls suiiiciently to prevent deadening of the vertical yielding ac tion of the cushioning bodies by the offset call: walls, substantially as described.

In testimony, that I claim the foregoing as my invention I afiix my signature in the presence of two witnesses, this 16th day of July, A. D. 1912.
